TikTok's algorithm exhibited pro-Republican bias during 2024 presidential race, study finds

A study found TikTok's algorithm recommended more Republican-aligned content during the 2024 US election. Republican accounts saw more like-minded content, while Democratic accounts were shown more opposing views. This suggests a pro-Republican skew.

TikTok, a widely used social media platform with over a billion active users worldwide, has become a key source of news, particularly for younger audiences. This growing influence has raised concerns about potential political biases in its recommendation algorithm, especially during election cycles. A recent preprint study examined this issue by analyzing how TikTok’s algorithm recommends political content ahead of the 2024 presidential election. Using a controlled experiment involving hundreds of simulated user accounts, the study found that Republican-leaning accounts received significantly more ideologically aligned content than Democratic-leaning accounts, while Democratic-leaning accounts were more frequently exposed to opposing viewpoints.

TikTok has become a major force among social media platforms, boasting over a billion monthly active users worldwide and 170 million in the United States. It has also emerged as a significant source of news, particularly for younger demographics. This has raised concerns about the platform’s potential to shape political narratives and influence elections.

Could it possibly be because Kamala Harris was a WOAT level candidate?

As more young people get news from influencers instead of traditional journalists, they will deliberately climb into echo chambers. They don't need to be prodded or anything.

I have several concerns about the study on TikTok’s recommendation algorithm and its potential political biases. First, I find that the framing of the abstract assumes TikTok’s political influence is inherently problematic without sufficiently contextualizing how it compares to other media platforms. Additionally, the study focuses only on three states—Texas, New York, and Georgia—which may not fully represent national trends, raising the possibility of confirmation bias.

From a methodological standpoint, I am skeptical about the use of sock puppet accounts to simulate user engagement. These artificial accounts may not accurately replicate how real users interact with content, which could skew the findings. Furthermore, the study does not clearly differentiate between the algorithm’s role in content distribution and organic user-driven engagement patterns. Without establishing causality, it’s difficult to determine whether the algorithm is biased or simply responding to user preferences.

Another issue I see is the labeling of political content. The study claims to have categorized nearly 400,000 videos, but it is unclear how this was done. If humans labeled them, was there consistency in their classification? If an automated system was used, was there any built-in bias?

I also question whether the study adequately accounts for TikTok’s frequent algorithm updates and the influence of external events. Political content consumption is highly dynamic, and shifts in the algorithm could be influenced by real-world developments rather than intentional bias.

Overall, while I think the study raises interesting questions, I believe its conclusions would be stronger if it incorporated real user behavior alongside sock puppet tests, expanded its geographic scope, and compared TikTok’s patterns to other platforms like YouTube, Twitter, and Facebook. Without these considerations, the findings risk being incomplete or misinterpreted.
